  • iPhone SKD make the iPod controller appear

    - by nico
    Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !

  • How to show a live Presentation from an Android phone?

    - by Pentium10
    This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

  • Moving the table view and keep the toolbar visible?

    - by Jakub
    Hello, In my view I have a toolbar with a button at the top and a table view underneath, like in the following picture: An you can see there are text fields in the cells of the table view. The problem appears when I want to edit the tet fields which are in the bottom of the table view. As you can imagine the keyboard overlaps the text fields. Let say I want to edit the fields in the C section, the result is following: I tried different approaches for moving the table view, but I always end up with the toolbar being hidden. In one cae the toolbar was moving up with together with the table view, in the second case the table view overlaps the toolbar: All the ideas how to move the table view to make the cell being edited visible together with having the toolbar visible? How to move/resize the table view? Thanks!

  • How to add new field(s) to the contact?

    - by user328302
    I want to add a Custom field to the ContactsContract content provider. I'm trying to build a Voip application and would like to add a SIP address(name@domain) field to it. What MIME type will I need to associate with it? Also I want to add a group address field which will have a list of group addresses in it (name@domain, name@domain,...). Wich MIME type will I have to associate with this type of field. I also want to add custom fields to the Call History like a session ID and SIP address(name@domain) field. How can I customize the call history? It'll be great if someone can give me an example.

  • How to do orientation rotation like built-in Calc app?

    - by Ray Wenderlich
    I'm trying to make an app that handles orientation/rotation similarly to the way the built-in Calc app does. If you check out that app, in portrait mode there's a normal calculator, and if you rotate to landscape mode there are additional buttons that appear to the left. I can't figure out how to do this by setting the autosize masks. The problem is the "normal" calculator view is 320px wide in portrait mode, but actually shrinks to around 240px in landscape mode to fit the additional controls. I've seen examples like the AlternateViews sample app that have two different view controllers (one for portrait and one for landscape), but they don't seem to animate the transitions between the views nicely like the Calc app does. I've also tried setting the frames for the views manually in willAnimateSecondHalfOfRotationFromInterfaceOrientation, but it doesn't seem to look "quite right" and also I'm not certain how that works with the autoresize mask. Any ideas how this is done? Thanks!

  • Custom Font. Keeping the font width same.

    - by user338322
    I am trying to draw a string using quartz 2d. What i am doing is, i am drawing each letter of the string individually, because each letter has special attributes associated with it, by taking each letter into a new string. The string gets printed, but the space between the letters is not uniform. It looks very ugly to read . I read someting about using custom fonts. But i have no Idea, if I can do it!! my code is here. (void) drawRect : (CGRect)rect{ NSString *string=@"My Name Is Adam"; float j=0; const char *charStr=[string cStringUsingEncoding: NSASCIIStringEncoding]; for(int i=0;i { NSString *str=[NSString stringWithFormat:@"%c",charStr[i]]; const char *s=[str cStringUsingEncoding:NSASCIIStringEncoding]; NSLog(@"%s",s); CGContextRef context=[self getMeContextRef]; CGContextSetTextMatrix (context,CGAffineTransformMakeScale(1.0, -1.0)) ; CGContextSelectFont(context, "Arial", 24, kCGEncodingMacRoman); //CGContextSetCharacterSpacing (context, 10); CGContextSetRGBFillColor (context, 0,0,200, 1); CGContextSetTextDrawingMode(context,kCGTextFill); CGContextShowTextAtPoint(context, 80+j,80,s,1); j=j+15; } } In the output 'My Name is Adam' gets printed but the space between the letters is not uniform.!! is there any way to make the space uniform!!!

  • iPhone: Same Rows Repeated in Each Section of Grouped UITableview

    - by Rank Beginner
    I have an app that is a list of tasks, like a to do list. The user configures the tasks and that goes to the SQLite db. The list is displayed in a tableview. The SQL table in question consists of a taskid int, groupname varchar, taskname varchar, lastcompleted datetime, nextdue datetime, weighting integer. I currently have it working by creating an array from each column in the SQL table. In the tableView:cellForRowAtIndexPath: method, I create the controls for each task by binding their values to the array for each column. I want to add configurable task groups that should display as the section titles. I got the task groups to display as the section headers. My problem is that all the task rows are repeated in each group under each header. How do I get the correct rows to show up only under the correct section? I'm really new to development period and took on a hobby of trying to teach myself how to develop iphone apps. So, pretty please, be a little more detailed than you normally would with a professional developer. :)

  • Moving UITableView cells and maintaining consistent data

    - by Mark F
    I've enabled editing mode and moving cells around to allow users to position table view content in the order they please. I'm using Core Data as the data source, which sorts the content by the attribute "userOrder". When content is first inserted, userOrder is set to a random value. The idea is that when the user moves a cell around, the userOrder of that cell changes to accomodate its new position. The following are problems I am running into while trying to accomplish this: Successfully saving the the new location of the cell and adjusting all changed locations of influenced cells. Getting the data to be consistent. For example, the TableView handles the movement fine, but when i click on the new location of the cell, it displays data for the old cell that used to be that location. Data of all influenced cells gets messed up as well. I know I have to implement this in: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath {} I just don't know how. The apple docs are not particularly helpful if you are using Core Data, as in my situation. Any guidance greatly appreciated!
